Three-dimensional image display apparatus

Abstract

A three-dimensional image display device including a polarized light module, a non-vertical polarized light barrier grating unit and an image display unit is provided. The polarized light module provides a polarized light. The non-vertical polarized light barrier grating unit is disposed in a light path of the polarized light to modulate the polarized light into a modulated polarized light in interlaced lines for output. The image display unit receives the modulated polarized light from the non-vertical polarized light barrier grating unit, and outputs two or more images with parallax.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 97139194, filed on Oct. 13, 2008. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to an image display technique. More particularly, the present disclosure relates to a three-dimensional image display technique.[0004]2. Description of Related Art[0005]According to a conventional three-dimensional image display technique, the three-dimensional image display can be achieved with utilization of a barrier. The barriers are mainly grouped into three types, i.e. energy barriers, polarized light barriers and color barriers. The conventional barrier-type three-dimensional display device mainly applies the energy barrier, and a structure thereof is shown as FIG. 1. FIG. 1 is a schematic diagram illustrating a convent...

AI Technical Summary

Benefits of technology

The present patent provides a three-dimensional image display device that includes a polarized light module, a non-vertical polarized light barrier grating unit, and an image display unit. The device can output two or more images with parallax. Additionally, the patent describes a dual-mode image display device that includes a polarized light module, a display unit, and a non-vertical polarized light barrier grating unit or a control device that can switch between a 3D mode and a 2D mode. The device can display both 2D and 3D images. The technical effects of the patent include providing a more immersive and realistic image display with improved depth perception and parallax effect.

Problems solved by technology

According to such method, switching between 2D and 3D display modes cannot be achieved, and disposing angles of a screen is limited, which can only be a vertical stripe parallax barrier.

The display effect of FIG. 2 is similar as that of FIG. 1, and the X-direction resolution is also decreased for a half, and switching between the 2D and 3D display modes cannot be achieved, and the disposing angle of the screen is limited, which can only be the vertical stripe parallax barrier.
